"You need to cover the water"

Translation: Unahitaji kufunika maji

[JosephPoli]

Is it possibly to use "kufunika" in the metaphorical sense? In english, you could say "I'll cover the beer" to mean "I'll pay for the beer", is there the same connotation in swahili?

Isn't there a formulation using the word "lazima"? I don't remember how this would sound.
